Article 1949
ART. 1949. The bailor shall refund the extraordinary expenses during the contract for the preservation of the thing loaned, provided the bailee brings the same to the knowledge of the bailor before incurring them, except when they are so urgent that the reply to the notification cannot be awaited without danger. If the extraordinary expenses arise on the occasion of the actual use of the thing by the bailee, even though he acted without fault, they shall be borne equally by both the bailor and the bailee, unless there is a stipulation to the contrary.
